Q- Two blocks of mass m and M are attached to the two ends of a light spring of constant k. The system is held by m such that M is suspended through the spring in air. Now the system is lowered slowly such that M just touches the tabletop and m is released. Find the maximum displacement of m before it comes to instantaneous rest.

Q- A small light disc is attached with one end of a spring of constant K, the other end is fixed to ground and stands vertical. a small block of mass m is dropped from a height h above the disc. Considering elastic impact and only vertical motion find the maximum velocity and maximum acceleration of the ball in consequent motion.
